I have been using Econco rebuilt tubes for some thirty years. There have been, perhaps, three times when tubes failed to perform as expected; each time Econco has honored their warranty. On one of those very rare occasions they actually went beyond the requirements of the warranty. The company and their personnel are among the most reliable and considerate with whom I have dealt. I use their 4CX15000 and 4CX5000 rebuilds.

Econco is not doing well on my tubes this year. 4CX15000A—tuned way different from Econco that came out, went back for replacement. Unfortunately, it was purchased through Richardson, so another layer of people to deal with. The 3CX15000A7 failed during tune up. They called and asked what I did to their tube, there was a hole in the grid…Replacement going in tomorrow. And a 4CX20000D. Went in per normal and has run almost 2 weeks. Time to perform filament voltage management this week.
The 2 Econco tubes that went in last year have been ok. 4CX20000D and 4CX20000C. And the YU-148 from Econco is over 18 months which is exceptional for that transmitter. One Freeland lasted 2 years, otherwise, 12-16 months is the norm.
Consistency seems to be the problem these days…As always, YMMV.

I did not have much luck with Protek either. Zonum was great for a while then they went downhill. I have used everyone out there at one time or another with decent results then they start slipping!! CPI used to be my rebuilt of choice but when they went away, .....another one bites the dust. I just put in the replacement Richardson sent me and so far it tuned up nicely and makes plenty of power. We will see in a week or two!!
All tubes are junk these days. Rebuilt even more so. I have been using Protek in a couple of transmitters with better than rebuilt life at about the same cost. If you are talking about buying a new Eimac... They are outlandishly priced and the last new Eimac tube that I installed didn't last much better than the rebuilds that had been ran previously.
